milanvirijevic/iStock(NEW YORK) — Parents longing to afford what some consider the holy grail of infant sleepers — which claims to calm fussy babies so they and their parents can sleep — can now rent it from the company at a fraction of the price.

The SNOO, a smart baby bassinet that hit the market in 2016, is now available to rent for $4.90 per day — roughly $147 per month (with a minimum of one-month rental). The original purchase price is a hefty $1,300 compared to other bassinets, many of which can be purchased for $100 or less.

“We are so excited to announce that parents across America can now rent SNOO for dollars a day!” Happiest Baby, the company that makes the SNOO, wrote on its Facebook page, where it claims that the bassinet “is the world’s safest, most effective baby bed.”

The SNOO was designed by Los Angeles-based pediatrician Dr. Harvey Karp, based on a theory from his book The Happiest Baby on the Block about “the 5 S’s” for soothing babies: swaddle, side or stomach position, shush, swing and sucking a pacifier.

The product promotes soothing with its womb-like rocking and white noise features. The SNOO automatically responds when a baby wakes up and reactivates sound and motion so they can be soothed back to sleep.

In the SNOO, a baby is swaddled on his or her back and secured with snaps. This keeps the baby from rolling into risky positions, the company’s website claims.

According to the American Academy of Pediatrics, the safest position for babies to sleep is on their backs. The maximum weight for a baby to use the SNOO is 25 pounds, but the company says the SNOO should only be used until 6 months or “until baby can get on hands and knees.”

“Once babies start rolling and sitting, which happens between 4 and 6 months, bassinets are not safe anymore,” said Dr. Edith Bracho-Sanchez, a board-certified pediatrician and Global Health Fellow at Stanford.

Parents have raved about the SNOO since its debut, including celebrity Ashton Kutcher, who reportedly brought it up on Dax Shepard’s Podcast, “Armchair Expert,” in 2018.

“He was like a 6-hour sleeper and I’m eternally grateful to the SNOO for that,” Kutcher said of his son Dimitri, whom he shares with Mila Kunis.

According to Happiest Baby, rental units are reconditioned before they’re sent out, which includes sanitizing and a safety check.

In a statement to ABC News’ Good Morning America, Karp said the SNOO rental “provide babies with this added safety for approximately the same cost of a daily coffee.”

According to Karp, SNOO did a survey with the parenting website BabyCenter, which indicated that sleep deprivation from babies crying is the number one stressor on new parents.

“We have many third-party university studies underway to demonstrate that we can reduce infant sleep death and postpartum depression,” Karp added. The status of those studies was not clear.

“Ultimately, our goal is to have insurance companies subsidize this rental, so that parents across the country can have access to SNOO at a very low price (just as they now have access to breast pumps, which are subsidized by the government and insurance),” he said.

Dr. Bracho-Sanchez said she urges parents to consider that some of the behaviors the SNOO tries to address are normal for newborns.

“Many babies are born with a flipped day-night cycle and it takes a few weeks for them to adjust to life out of the womb,” Bracho-Sanchez told GMA. “During that time they may cluster feed at night and these feeds provide essential nutrition. I would hate for parents to fall into a false sense of reassurance that their baby’s needs have been met.”

She went on, “There is also such a thing as the crying curve–babies are known to cry the most around two months of age. This typically coincides with colic, which is very common in babies. The shushing, swaddling and swinging may work, but it also may not.”

Bracho-Sanchez also took issue with strapping babies down, as is done with the SNOO.

“Babies also start rolling from their tummy to their back at or around 4 months of age, not before, and it takes them another month or so to roll from their back onto their tummy,” Bracho-Sanchez added. “So if the baby is put on his or her back to sleep and the sleeping environment is kept free of pillows, soft bedding, toys, or any other choking hazard, I don’t believe strapping babies down is necessary.”

But she applauded the SNOO for encouraging parents not to co-sleep with their infants.

“I applaud any efforts to get parents to put their babies on their back to sleep and to avoid bed sharing, the SNOO included,” she added.
